摘　　要：渣热利用对于硫铁矿制酸企业在清洁生产、环境保护、资源综合利用、热能回收等方面具有重要意义。介绍一种新型的硫铁矿渣热回收利用技术,分析渣热回收方式和热回收利用效率,提出了渣热利用在设计上有关腐蚀、磨损等方面的问题,并进一步探讨了硫铁矿渣热利用自动化可控程度和成套设备。本成果有助于硫铁矿制酸领域的节能减排,并可为其他领域的渣热利用提供借鉴。The utilization of slag heat from preparation of sulfuric acid from pyrites is important for cleaner production, environmental protection, resource comprehensive utilization and heat energy recycle. A new recovery technique of pyrite slag heat is introduced, the recovery mode and efficiency of slag heat are analyzed, the problems of corrosion and abrasion during the slag heat recovery are presented, and the whole set equipment and the controllable possibility of automatization are discussed. The technique is profitable for the energy saving and emission reduction in the field of industrial production of sulfuric acid, and can provide reference for the heat recovery of slag in other fields.
